This protocol describes in detail how to specifically transfect different regions in the C57BL/6 central nervous system via in utero electroporation. Included in this protocol are detailed instructions for transfections of regions that develop into the cortex, hippocampus, thalamus, hypothalamus, lateral septal nucleus and striatum.

Despite the functional and medical importance of the hypothalamus, in utero genetic manipulation of its development has rarely been attempted. We show a detailed procedure for in utero electroporation into the mouse hypothalamus and show representative results of total and partial (regional) hypothalamic transfection.

The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system. The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

Diencephalon: Thalamus and Information Relay

2025
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological states or needs.

Generation of Medial Thalamus-Anterior Cingulate Cortex Slices from Mouse Brains

The video demonstrates the preparation of medial thalamus-anterior cingulate cortex (MT-ACC) slices from mouse brains. A mouse's brain is dissected, cuts are made to expose the MT-ACC pathway, and slices are generated using a vibratome. The MT-ACC slices are then maintained in oxygenated artificial cerebrospinal fluid.
FAQs
The thalamus functions as a selective relay rather than a passive conduit. By directing most sensory information toward the cerebral cortex, it contributes to how incoming signals are organized for cortical processing. Its involvement in attention and sleep also means that the flow and availability of sensory information can change with behavioral state, influencing perception and responsiveness.
The hypothalamus links neural signals with hormonal regulation by controlling the pituitary gland. This connection allows brain activity to influence endocrine responses, while hormonal signals can contribute to physiological regulation. Studying this pathway helps explain how the nervous system participates in stress responses, internal balance, and disorders involving abnormal hormone regulation.
Their contributions are complementary. Thalamic circuits help regulate sensory availability, attention, and sleep, whereas hypothalamic circuits integrate neural and hormonal information related to temperature, hunger, autonomic activity, and stress. Considering both regions shows how changes in environmental information and internal physiological state can be coordinated rather than regulated as separate processes.
Motivated behavior depends on coordination between information processing and physiological need. The thalamus contributes to the handling of sensory signals and behavioral state, while the hypothalamus represents internal conditions such as hunger, temperature, and stress. Their interaction provides a neural context in which bodily needs can influence attention, responses, and behavior.
Research can investigate how sensory processing, sleep, endocrine signaling, autonomic activity, and homeostatic regulation interact within the nervous system. Examining the regions together is useful when a question crosses the boundary between brain activity and body regulation. This perspective supports studies of sleep disorders, hormonal disease, emotional regulation, and sensory-processing conditions.
These regions are relevant to several research areas identified in neuroscience, including sleep disorders, hormonal disease, emotional regulation, and neurological conditions involving sensory processing or homeostasis. Their broad influence makes them useful targets for examining how disrupted circuits may affect both physiological control and behavior, rather than producing effects limited to one isolated function.
